JOHN HIERS, OF CONNERSVILLE, INDIANA, ASSIGNOR OF ONEHALF JAMES N. HUSTON, OF SAME PLACE.

MACHINE FOR CUTTINGLOCKS EN HOOPS.

SPECIFICATION forming part of Letters Patent No. 391,610, dated October 23, 1888.

Application filed July 6, 1887. Serial No. 243,567.

To all whom it may concern:

Be it known that I, JOHN HIERS, of the city of Connersville, county of Fayette, and State of Indiana, have invented certain new and useful Improvements in Machines for Out ting Locks in Hoops, of which the following is a specification.

The object of my said invention is to provide a means by which the locks in hoops for barrels and other vessels may be quickly and accurately cutat a single operation. This object is accomplished by a machine provided with a knife of the general formof the lock to be out, which knife is mounted on a reciprocating base mounted in slides, said slides being preferably at something of an angle, as shown, and said base being most commonly operated in one direction by a treadle and in the other by a spring, all as will be hereinafter more particularly described.

Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure 1 is a perspective view of a ma chine embodying my said invention; Fig. 2, a central vertical section of the upper portion of the machine on an enlarged scale; Fig. 3, a View looking upwardly from the dotted line 3 3 in Fig. 2, and Fig. 4 a detail section on the dotted line 4 4.

In said drawings the portions marked A represent the frame of the machine; B, the knife; 0, the treadle by which the knife is operated, and D the spring by which it is returned to position.

The frame A is of any suitable design, that which is shown being of a desirable form. Slides a are secured to the sides of its upper portion, in which the base for the knife B is mounted. These slides, as before stated, are preferably set at an angle, as shown, as this causes the knife to cut at a corresponding angle, and the hoops are more conveniently held at about this position while being operated upon than at any other. Just below the knife is a head, A, in which is preferably inserted a piece of endwise wood, a, which serves as a cutting-block, against which the edge of the knife comes in operation.

(No model.)

The knife 13 is of the form of the lock which is to be cut in the hoops, as shown most plainly in Fig. 4:. It is securely fastened by means of bolts or otherwise to a base, B, which is mounted in the slides a and is adapted to move therein.

The treadle C is an ordinary treadle, as shown, and is connected by the rod 0 to a projection, b, on the base 13 of the knife, and is thus adapted to operate said base and the knife thereon, as will be readily understood.

The spring D is preferably of the general form shown, although many other forms of springs might be employed. It is mounted on the frame A and attached to the upper end of the knife-base B, and thus operates, when the pressure on the treadle has been released, to return the knife to the position shown in the drawings, ready for another operation. A spring, cl, is also preferably employed, which is attached at one end to near the lower part of the spring D, and at the other to the rear point of the projection b on the base B, which operates to hold said base back against the rear sides of the slide and prevent any rattle between said base and the slides.

By the use of this invention the operator is enabled to rapidly and accurately form locks on wooden hoops without reference to their size or character, it'being only necessary to hold the hoop to the desired position with his hands and then press down on the treadle with his foot a single time to completely form the lock.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. The combination, in a machine for cut ting locks in hoops,-of the frame, the inclined slides at the top of said frame, the knife mounted on a suitable base and arranged to operate in said slides, a treadle connected by a rod to the rear side of the base of said knife, and a spring, D, also connected at one end to said base and to the frame at its other end, where by said knife is returned after being operated by means of the treadlc, substantially as set forth.

2. The combination, in a machine for cutting locks in hoops, 0f the frame, slides on In witness whereof I have hereunto set my said frame, the cutting-knife mounted to 0phand and seal, at Gonnersville, Indiana, this erate in said slides, the means, substantially 29th day of June, A. D. 1887.

as described, for operating said knife, and the JOHN HIERS. [L. s] spring d, attached to the base ofsaid knife, Witnesses:
